To @ZZ 'whom it may con/cern: the interlocking coils; but the several coils Be it known that I, AUGUSTUS ALLGOEVER, are left wholly without lateral support, so as of the city, county, and State of New York, to be free to give and play loosely inter se in have invented anew and useful Improvement a direction transversely to their length. To 55 5 in lVoven-IVire Mattresses or Bed-Bottoms; limit the depression and extension or sagging and I do hereby declare that the following is a of these several longitudinal coils under the full and exact description thereof, reference strain of a weight thereon and to afford them being had to the accompanying drawings, and at the same time transverse support, I place to the letters of reference marked thereon, under said woven-wire mattress a metallic 6o lo making a part of this specification. re-enforcing web or netting D, formed of a My invention relates to woven-wire matseries of interwoven or interlocked wires setresses or bed-bottoms, and has for its object cured to the frame upon which the mattress to re-enforce the same and prevent such an B is secured, so that the wires in said re-enexcessive sagging thereof as will have atendforcing web shall severally extend in a direc- 65 15 ency to strain the coils and produce their tion transversely to that of the spiral coils in permanent elongation. the superimposed mattress and the web have It consists in combining with the wovena firm support upon each end of the mattress. wire mattress an underlying, undergirding, By preference the interwoven wires of the supporting web or netting of interwoven netting D are severallybentin zigzag fashion, 7c 2o wires, which are free to yield in the direction each to form a succession of flattened coils or of the length of the coils of the mattress to loops c c, comparatively non-elastic in their an extent sufficient to allow a proper elastic length, as shown in Figs. 1 and 2. They may, play in said coils and no more, and will therehowever, be formed in spiral coils, as shown upon afford an unyielding support for the in Figs. 3 and gt, to form elastic strands which 75 2 5 mattress under every part thereof, so as to reshall be stretched to extend transversely to sist its undue depression or straining either the length of the coils of the mattress. In in the direction of the length of its coils or either case they are left loose and free to move transversely thereto. independently in the direction of the length In the accompanying drawings, Figure l is of the coils of the mattress B, their play or 8o 3o a bottom View of my improved 11e-enforced freedom of movement being, however, so limwoven-wire bed-bottom; Fig. 2,alongitudinal ited as that they will only give or yield far section thereof in line x a; of Fig. 1; Fig. 3, a enough to allow a depression of the supersimilar detached section illustrating a modiimposed mattress to the extent required in a iication in structure of the re-enforcing netproper elastic play thereof, whereupon they 85 3 5 ting; Fig. 4, a similar section illustrating the will so engage each other as to afford an unfunction of the re-enforcing netting in supyielding support to the mattress, as shown in porting the mattress when it is depressed; Fig. 4.

The elastic in an exaggerated form at e c in Figs. l, 2, woven-wire web of the mattress is constructed, and 3, whereby an independent motion thereof 95 4 5 as is usual, of interwoven strands of spirallyis permitted until the open spaces between coiled spring-'steel wire, the coils being made them are closed by the contact of the interpreferably to extend the length of the matlocked strands, as shown in Fig. 4, and by setress.

As a modification of my invention, the supporting: or re-eni'orcing Web or netting D, to be combined With the Woven-Wire mattress B as an undergirding therefor, may be constructed of a metallic net or mailD, composed of a series of separate interlocking links ff, as shown in Fig. 5.

I claim as my invention- 1. The combination, in a mattress, with a suitable supporting-frame, of the independent Woven-Wire fabrics stretched upon said frame one above the other, with the length of the coils in the one disposed at right angles to the coils in the other, substantially in the manner and for the purpose herein set forth.

2. The combination, with a Woven-Wire mattress and a frame-Work for its support, of a' system of loosely interwoven or interlocking longitudinally-bent Wires stretched under the
